6 Claims.

This invention relates to an improved construction of roller screen for windows and more particularly to a roller screen construction especially adapted for use on windows provided with sliding sashes.

It is a primary aim of the invention to provide a device adapted for use on window frames of various widths and lengths in conjunction with window screens of various sizes, for mounting spring shade rollers of various lengths on which the screen is adapted to be wound.

Still another aim of the invention is to provide a window screen having means whereby the screen fabric may be wound on a roller, when not in use, and disposed within a cover to protect the screen from the elements, said cover being yieldably mounted by resilient brackets in window frame openings on the outer sides of the window sashes in a manner so that the cover and window screen may be readily lifted out of their supporting brackets from the inner side of the window when it is desired to entirely remove the screen from the window, as during the winter season.

Still another aim of the invention is to provide a novel construction of roller window screen including a cover formed of extensible, telescoping sections for receiving the window screen when in a retracted position, and guide members formed of extensible, telescoping sections having channel portions for slidably engaging the side edge of the window screen when in an extended position.

Other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawings, which illustrate a preferred embodiment of the invention, and. wherein:

Figure 1 is a front elevational view showing the invention applied to the outer side of a window frame and in an extended position,

Figure 2 is an enlarged longitudinal vertical sectional view taken substantially along the plane of the line 22 of Figure 1,

Figure 3 is a horizontal sectional view on an enlarged scale, taken substantially along the plane of the line 3-3 of Figure 1,

Figure 4 is an enlarged vertical sectional view taken substantially along the plane of the line 4-4 of Figure 1,

Figure 5 is a fragmentary, enlarged horizontal sectional view, taken substantially along the plane of the line 55 of Figure 1,

Figure 6 is a fragmentary view of a portion of the screen fabric,

Figure 7 is a vertical sectional view, partly in elevation, of one of the latch members, and

Figure 8 is a horizontal sectional view taken substantially along the plane of the line 8-8 of Figure 7.

Referring more particularly to the drawings, wherein like reference characters designate like or corresponding parts throughout the difierent views, I9 designates generally a conventional window frame including a sill l I and side rails I2 in which are slidably mounted a pair of sashes 13. These elements, being of conventional construction, are shown merely to illustrate the application of the improved window screen, designated generally l4, and comprising the invention.

The window screen construction l4 includes a hollow roller I5, as best seen in Figure 5, through which extends a shaft l6 which is provided with a round end I! and a square end l8, which ends project beyond the ends of the roller l5. A spiral spring I9 is mounted on the shaft l6 and is fixed at one of its ends by means of a fastening 20 to the shaft I 6 and at its opposite end by means of a similar fastening to the roller l5 for turning the roller in one direction relatively to the shaft. An elongated strip of mesh wire fabric 2| is secured at one end to the roller l5 and is wound therearound in a direction so that when the roller I5 is actuated by the spring I9 it will wind the fabric strip 2| thereon. The strip 2| is provided with enlarged reinforced side edges 22 which are likewise flexible to be wound on the roller IS. The free end of the strip 2| is mounted in and secured to to a rigid channel shaped member 23 by means of the fastenings 24. A cover, designated generally 25, is formed of an intermediate section 26 and a pair of corresponding end sections 21 which are disposed in telescopin engagement with the ends of the intermediate section 26 to provide the extensible cover 25. The cover sections 26 and 21 are rolled lengthwise to form a restricted slot 28 in the under side of the cover 25. The intermediate section 26 has its longitudinal edges rolled outwardly to form the portions 29 in which are slidably mounted the inwardly curved longitudinal edges of the sections 21, which form the portions 30. As best seen in Figure 5, the remote ends of the sections 21 are closed by the walls 3|. A roller bracket 32 is mounted in one of the sections 21 and a roller bracket 33 is mounted in the other section 21. The roller brackets 32 and 33 each include a flange 34 which extends toward and is secured to the inner side of a wall 3|, as by means of soldering, as at 35. The brackets 32 and 33 each include a plate portion 35 which is spaced inwardly from the wall 3| of section 21, in which it is mounted. As best seen in Figure 4, the plates 36 are each provided with upwardly diverging slots 3'! which open outwardly of the upper edge thereof and which terminates at its lower, restricted end in a restricted slot. The restricted slot of the bracket 32, designated 38, is sized to loosely engage the end ll of the shaft HE. A restricted slot 39 of the bracket 33, as best seen in Figure 5, is substantially larger and is provided with parallel sides to snugly engage opposite sides of the squared end |8 of the shaft Hi to thereby key the shaft is to the cover 25 so that the roller l5, when actuated by the spring 19, will turn relatively to the shaft l5. W A pair of corresponding guide members, designated generally 45, each includes a strip 4| and a strip 42 of sheet metal. The strips 4| and 42 are bent lengthwise to form base portions 43 and the channel portions 24. The base portion 43 and channel portion 46 of each strip 42 is slidably mounted in the portions 43 and 44, respectively, of the complementary strip 6|. It will thus be seen that the connected strips 2| and 42 combine to form extensible base members 45 which are adapted to be disposed in the inner faces of the side rails l2, on the outer side of the sashes Hi, and to be secured to the rails |2 by means of fastenings 46 which extend through the base portions 63 and which hold the strips 4| and 42 of each of the base members 45 in adjusted positions. The two base members 45, before being secured by the fastenings 46 to the rails 2, are adjusted to the same length, and

are attached so that they are disposed in opposed relationship to each other with the channel portions 44 thereof extending inwardly of the opening of the window frame H). The upper sections 42 of each of the base members 55 are provided with outwardly extending flanges 41, as best seen in Figure 4. Referring back to Figure 3, the guides 45 also include the extensible guide members 48 formed of telescoping sections 49 and 50, each of which are formed of an elongated stripof sheet metal folded lengthwise and with each of the'sections 55 mounted within the complementary sections 35. The intermediate portion of the pairs of sections 49 and 50 are compressed to form the shank portions 5| of the guide members 48, which shank portions are mounted in the channel portions M of the base members 35. The longitudinal edges of the pairs of strips 29- and 59 are shaped to form inwardly opening channel portions 52 to slidably receive the edges 22 of the screen 2|. The channel portions 52 are provided with restricted outer ends to prevent the edges 22 from being detached therefrom except through the upper ends thereof. The channel members 48 are extended to substantially the same length as their supporting base members 45, after which they are secured in adjusted positions by means of fastenings 53, which extend through alined drilled apertures 54 in the channel portions 4| of the shank portions 5|, to secure guide members 48 to the base members 25 to thereby fixedly mount eachv of the guides '32 on a side rail |2. The upper sections 52 of the guide members 48, at their upper ends, extend above the channel portions 44 and are bent to form upwardly opening channel members 55 which rest on the flanges 41 and on which are adapted to be mounted the portions 29 and 35 of the ends of the cover 25 to thereby aline the slot 28 with the channels 52.

As best seen in Figures 2, 7 and 8 the sill H is provided with one or more stationary keepers 56, each of which is provided with an upwardly offset intermediate portion 51, having an opening 58 provided with an outwardly projecting slot 59, in communication therewith. A corresponding number of latch elements 69 are mounted on the inner side of the member 23. Each of the latch elements 65 includes a support and bearing member 6| in which is journaled a stem 62 having a depending lower end provided with an outwardly projecting lug 63. A handle 5 is secured by a fastening 55 to the upper end of the stem 62 to combine with the lug 83 for retaining it in engagement with the support and bearing 6!. The handle 64 is primarily adapted to be used for turning stem 62 to aline the lug $3 with the slot 59 of the complementary keeper 56, so that said lug may pass through the slot 5-9 as the stem moves in to the opening 58 after which the handle 54 may be turned in either direction to move the lug 63 out of registry with the slot 59 and thereby latch the member 23 to the sill H to hold the screen 2| in an extended position, as illustrated in Figure 2.

A strand of wire 66 is associated with each of the guides 45. Each of the strands of wire 65 is provided with a looped end 51 forming an eyelet to receive a fastening 6B for securing the strand to a rail |2 on the outer side of the cover 25, and adjacent the top thereof. The strand 56 extends downwardly from the looped end 57 around the lower portion of the outer side and end of the cover 25- and through a space 69, as seen in Figure 1, behind the flange 41. The intermediate portion of the strand 55 is folded back upon itself to form a shank portion Ill which extends downwardly along the inner side of the channel portion 4| of the guide member 58, with which it is associated, and is provided at its lower end with an eyelet The eyelet H of the shank 10 is secured by a fastening 12 to the aforementioned rail l2 and to the base portion 23, through which the fastening 12 extends. The opposite end 13 extends upwardly and terminates beneath the horizontal center of the cover 25. The end 13 resiliently engages the inner side of the cover 25 to cooperate with the opposite end of the strand 66 to form a resilient bracket 14 which resiliently retains the end of the cover 25 in engagement with the channel member 55. It will thus be seen that the pair of brackets 74, as illustrated in Figure 1, resiliently hold the cover 25 in place on the upper ends of the guides 40 and provides means whereby the cover 25 may be removed readily from the window frame IE! but only through the inner side thereof, when the sashes I3 are both lowered, so that the cover 25cannot be removed from the. outer side of the window frame to thereby prevent the cover and screen being removed by an unauthorized person.

The end of the reinforcing member 23, which is connected to the free end of the screen 2|, terminates adjacent to the guides 48 to combinetherewith to retain the side edges of the screen 2| in the channel portions 52. The member 23, at its lower end, is of suflicient width so that it will not pass through the passage 28 to thereby provide means to be grasped for drawing the screen 2| outwardly of the cover 25, when the screen is in a fully retracted position. The member 23 thus retains portions of the side edges of the screen 2| in engagement with the channels 52, when the screen is in a fully retracted position, and also closes the passage 28 so that the screen 2! will be protected from the elements when not in use and when disposed within the cover 25.

Assuming the screen 2! to be in a retracted position, wound on the roller 25, the reinforcing member 23 may be grasped to extend the screen and to close the space between the guides 46, cover 25 and sill H by pulling the screen downwardly until the member 23 is in abutting engagement with the sill ll, after which latch members 68 are connected to the keepers 56 to thereby retain the screen in an extended position. When the screen is thus moved toward its extended position the roller I5 is turned in a counterclockwise direction, as seen in Figure 2, thereby causing the spring !9 to be tensioned so that when the latches 68 are released the spring I9 will rewind the roller I5 in a clockwise direction to move the screen fabric 2| to a fully retracted position. In this latter position, as heretofore described, the screen is protected from the elements and may be removed with the cover from the brackets 74 through the inner side of the window frame It, for storage, as for example, during the winter season when the screen is not required. The guides 40 may be left in place, or, if desired, may likewise be removed by removing the fastenings by means of which they are attached to the rails l2.

It will be obvious that rollers l5 of various lengths may be used with strips of screen fabric 2| of different widths to accommodate window frames of different widths and the cover 25 may be extended or retracted to adapt it to window frames of different widths. The device may also be mounted for screening a portion of the opening of a window frame or for screening the entire opening and the guides 40 may be extended or retracted to accommodate the device to window openings of different lengths and to provide means whereby different portions of the window opening may be screened.

Various modifications and changes are contemplated and may obviously be resorted to as only a preferred embodiment of the invention has been disclosed.
